Imo, Compared with Storm Gate, ZeroSpace look more geared towards SC2 fans compared to SG that is more WC3 with trees that serve as removable obstacles.
In a competitive RTS game where there can be multitude of different units in the hundreds you need to be able to tell the difference between. Else its just a messy blob that you attack move into and theres no skill or strategy, just a spray and pray. Visual clarity is extremely important otherwise the game feels bad to play and the competitive scene will die instantly cause no spectator can understand whats going on.
